Invisible Platform

[WhiteDeath]

How can I make my own invisible platform(or edit the one existing).
I want to make it longer like a bridge and tilted, so I exported it opened it with magos moved the vertexes to the desired shape, imported it in game but it does not work it still raises the unit in the same area as a unedited invisible platform.
I think I have to edit something else than the vertexes.

It's because the pathing map, it is still like the standard one, it has nothing to do with modelling. There are some tutorials that explain, how to make your own pathing map, but I don't find them right now.
